If you are a nonfiction writer, there are seemingly endless resources for publishing articles. I say "seemingly" because numbers are deceptive. Getting a nonfiction article published in a reputable magazine can be just as daunting as publishing a short story in The Atlantic. Unless you are a recognized expert in your field, the competition will be fierce.
But what if you are an unrecognized expert? Let's say you are a gardener with years of experience with soil types, plant requirements, vegetable varieties that do well or poorly in certain climates. Having a degree in horticulture doesn't add to your qualifications. The same holds true for numerous areas in which experience counts more than public recognition: raising children, raising chickens, dealing with aging parents, marketing your own crafts, and so on. I am sure you can think of several areas in which you have a body of knowledge that would be beneficial to others.
Internet sites that will pay for your articles
The best way to capitalize on that knowledge is to write articles on highly trafficked sites on the net. How does it work? Some sites offer writers a share of the income generated by ads on their site. Others give you a set payment for a certain number of clicks.
Here are two income-generating sites:
